Front Derailleur with 38.2 clamp for a 3x9 speed.

Hello,

I am just asking a quick question.. so have anyone know if there is a front derailleur with 38.2 clamp and 3x9 speed that exist in any shop? because i was able to find most of front derailleur with 38.2 for a 3x10, but not 3x9. the problem is i dont know if the 3x10 front derailleur could work with a 3x9 setup. i am also aware of the chain for a 9 speed is a bit more wide than 10 speed chain. well excuse my foul word.. i think that the world of mountain bike is really FU*KED UP but much more worse than i thought. so it won't be easy to find the right front derailleur. *sigh* if this offended you, then i apologized for my foul word.

so i will be waiting to hear from your reply and questions if you have some. i would appreciate your help on this matter. thanks in advance.

I assume that is on an MTB.

II think the 9 and 10 speed derailleurs are similar (front and rear), so I'd try the 3x10.

The three common diameters for seat tubes, and thus front derailleur clamps, are:
  • 28.6 mm, common on steel frames
  • 31.8 mm
  • 34.9 mm


9-speed and 10-speed front derailleurs are available in all three sizes. Some front derailleurs, like the Shimano Altus M370 and M371 models, come with shims so the same one will fit any of the three common seat tube sizes.
